The Michigan History Project released more than 90 photos of John F. Kennedy on an old-fashioned whistle-stop campaign tour through Michigan, taken just hours after making his famous Peace Corps speech at the University of Michigan on October 14, 1960.

The rare photographs of the tour through 10 cities were taken by Doug Fulton, who worked for the Ann Arbor News from the mid-1950s to the early 1980s, according to the Michigan History Project.

When Fulton retired, he moved to Arizona, where he and his wife lived until he passed away in 1996.

The organization's president, Alan Glenn, said they received a tip years later that Fulton may have possessed some worthwhile photographs from his time with the newspaper. They then got in touch with his widow, whom Glenn estimated to be about 90 years old.

"It turned out that there was a largish collection of his negatives in Arizona, being kept at his home where his widow still lived," Glenn told InsideEdition.com. "I don't think she remembered that there were any pictures of JFK in the collection. I'd guess that it was a case of something being stored away and forgotten about."

Despite finding no information other than the negatives labeled simply, "JFK," researchers were able to piece together information, and identify landmarks like the Kellogg Auditorium in Battle Creek, and the State Capitol in Lansing.

"There's all sorts of historical treasures out there, forgotten and packed away in attics and garages," Glenn said. "You've got to go out and find this stuff before it's tossed in the trash. Because when history is lost, it's gone forever."

The photographs will be collected into a larger project with the mission of preserving the state's history for generations to come.
